The word(s) "firon's" appears 15 time(s) in 15 verse(s) in Quran in Muhammad Habib Shakir translation.

(11) And firon's wife said: A refreshment of the eye to me and to you; do not slay him; maybe he will be useful to us, or we may take him for a son; and they did not perceive.

(12) And a believing man of firon's people who hid his faith said: What! will you slay a man because he says: My Lord is Allah, and indeed he has brought to you clear arguments from your Lord? And if he be a liar, on him will be his lie, and if he be truthful, there will befall you some of that which he threatens you (with); surely Allah does not guide him who is extravagant, a liar:

(13) So Allah protected him from the evil (consequences) of what they planned, and the most evil punishment overtook firon's people:

(14) The fire; they shall be brought before it (every) morning and evening and on the day when the hour shall come to pass: Make firon's people enter the severest chastisement.

(15) And certainly the warning came to firon's people.
